I personally found that I don't like the only clean lows and only mid/top drive recipe.
I think it sounds fizzy and wrong.
I also found that some drive pedals works great just as is blended with clean signal, without it sounding like theres a clean signal sitting on top of the drive signal or vise versa, and without it getting muddy, where as others requires some EQ to the drive sound to blend in nicely, depending on the inherrent character of the drive pedal in question and which kind of drive effect exactly you are trying to obtain.
Some drive pedals do require a small low cut, others a mid hump, others again a mid scoop, to sit nicely in the mix.
That said it probably helps my cleans to blend in nicely that they are not actually all that clean but overdriven, by a preamp that sits after my drive setup, giving the clean signal natural compression, and helping the drive signal blend in more smoothly as well, since it too is running through the same overdriven preamp.
